Okay I see that I could have provided more info that would help you guys help me. I throw RHBH except for a few tomahawks and forehands to get out of trouble. Most of my approach shots are pretty conservative but I'm comfortable making a run at a basket under 100'. Approaches are probably the best part of my game.
Not much success with any wide rim driver. Best drives are almost always low and fast but I finesse a lot of upshots with a nose up attitude that usually die near the basket.
Writing this makes me realize that what I'm looking for most is to be more consistent with speed 6 and higher discs. More distance would be nice but not a primary goal. Distance should improve with better mechanics.
I need a bag that helps me work on form issues without taking all the fun out of it.
With this in mind I'd suggest starting with these molds:
Stalker/TL - straight, controlled distance - maybe turnover?
Teebird/Eagle-X - light-to-medium wind and predictable fade
These will give you a baseline to tweak from and find fairways that really work for you. I'd suggest starting with fairways when building drivers into a bag, you pick what gives you accurate distance, then find the molds that plug the gaps for the longer bombs***this is just IMO though, not saying it's the only or best way.
After figuring out your fairways, add those faster discs that need more room to work.
Mids:
Buzzzzzzzzzzzzzzz. It's straight, it's neutral stability, you can figure out if you want to build your bag around it, or ditch it for a couple of molds a few degrees different. You can throw it nose up for straight-with-fade, level for dead straight accuracy, and it will hold any line if you anny or hyzer it. Even if it doesn't make the bag, it will definitely give you a more clear picture of the type of discs you work well with.
*build the rest of the mids based on what utility you find with the buzzz. typical complements are [understable] Fuse/Comet/Coyote and [overstable] Hornet/Wasp/KCProRoc. Don't be afraid to combo different mids for a week or so, find the best grouping to throw with so you can get out of bad situations AND capitalize on good ones*
Putters:
Totally dependent on your style and grip. Though I will say add a Rhyno or Wizard for overstable approach duties, or for approach shots thrown with more snap that need to sit down.
Again, this is just how I'd start building, no proof of success or science behind it, so take it with a grain of salt. Though I'd start with the putters (contrary to post order) and work progressively further from the basket.
Hope this helps
